 # Using Explicit Want to Start an Ability
 
+When a user touches a button in an application, the application often needs to start a UIAbility component to complete a specific task. If the **abilityName** and **bundleName** parameters are specified when starting a UIAbility, then the explicit Want is used. Using Explicit Want
 
-When a user touches a button in an application, the application often needs to start a UIAbility component to complete a specific task. The following describes how to use explicit Want to start a UIAbility component in an application.
-
-
-## How to Develop
-
-1. In a project of the stage model, create an ability and a page, named **callerAbility** and **Index.ets**, respectively. Use the **windowStage.loadContent()** method in the **onWindowStageCreate** function in the **callerAbility.ts** file to bind the two.
-   
-   ```ts
-   // ...
-       // callerAbility.ts
-       onWindowStageCreate(windowStage) {
-           // Main window is created, set main page for this ability
-           console.info('[Demo] EntryAbility onWindowStageCreate')
-           // Bind callerAbility with a paged named Index
-           windowStage.loadContent('pages/Index')
-       }
-   // ...
-   ```
-
-2. Repeat the preceding operation to create another ability named **calleeAbility**.
-
-3. Add a button to the **Index.ets** page of **callerAbility**.
-   
-   ```ts
-   // ...
-     build() {
-       Row() {
-         Column() {
-           Text('hello')
-           .fontSize(50)
-           .fontWeight(FontWeight.Bold)
-           // A new button with will call explicitStartAbility() when clicked.
-           Button("CLICKME")
-           .onClick(this.explicitStartAbility) // For details about explicitStartAbility, see the sample code below.
-           // ...
-         }
-         .width('100%')
-       }
-       .height('100%')
-     }
-   // ...
-   ```
-
-4. Override the **onClick** method and use explicit Want to start **calleeAbility** in the method. The **bundleName** field can be obtained from the **AppScope > app.json5** file of the project. The **abilityName** field can be obtained from the **yourModuleName > src > main > module.json5** file of the corresponding module.
-   
-   ```ts
-   import common from '@ohos.app.ability.common';
-   
-   // ...
-     async explicitStartAbility() {
-       try {
-         // Explicit want with abilityName specified.
-         let want = {
-           deviceId: "",
-           bundleName: "com.example.myapplication",
-           abilityName: "calleeAbility"
-         };
-         let context = getContext(this) as common.UIAbilityContext;
-         await context.startAbility(want);
-         console.info(`explicit start ability succeed`);
-       } catch (error) {
-         console.info(`explicit start ability failed with ${error.code}`);
-       }
-     }
-   // ...
-   ```
-
-5. When you touch **CLICKME**, the corresponding page is displayed.

+The user touches a button in the application to start the UIAbility component to complete a specific task. To start the UIAbility component in explicit Want mode, the **abilityName** and **bundleName** parameters must be specified.
